The Empirical Analysis of Technology Innovation Network Evolution Based on Patentometrics
Technology innovation network is very significant to understand and analyze the evolution of innovation technology area, and to observe the technology cooperation innovation and differentiated competition among enterprises.Considering patent data is the leading performance of the technology innovation, the paper adopted patentometrology analysis, social network analysis, visualization analysis and patent coupling analysis method and collected patent data for nearly thirty years in the field of electric vehicles so as to study the technology similarity evolution and technology cooperation evolution of the technology innovation network in this field, and display the results with data and graphs visually.By the analysis, we can conclude the hot spot and trend of development of technology in this field, the representative enterprise, and the change of cooperation between enterprises, which can provide the basis for enterprises to choose technology development direction and partners.The thought and method adopted in this study can also be used for analysis in other fields, which can provide the reference for the research of information technology.
